An acronym meaning : Please Tell Me If You're Coming Or Not

Typically used by people to replace the French term RSVP (Respondez S'il Vous Plait) which only means please respond.
Chuck: *answers phone* Hello?

Tom: Yo, I'm calling to tell you I will absolutely never go to your birthday party!

Chuck: Rude much, you only needed to call me if you were gonna come.

Tom: Naw, you said RSVP, if that were the case you shoulda said PTMIYCON

Chuck: Tom. . . STFU you literal bastard. *Hangs phone up*
